Models of L-Band Radar Backscattering Coefficients Over Global Terrain for Soil Moisture Retrieval
TL;DR: Physical models for radar backscattering coefficients are developed for the global land surface at L-band (1.26 GHz) and 40 ° incidence angle to apply to the soil moisture retrieval from the upcoming soil moisture active passive mission data.
Journal ArticleDOI

TL;DR: In this paper, in situ observations are used to examine differences in the sensitivity of the 3-km radar versus the 36-km radiometer measurements to the landscape freeze/thaw state during the period of overlapping instrument operation.
Journal ArticleDOI
The Effects of Layers in Dry Snow on Its Passive Microwave Emissions Using Dense Media Radiative Transfer Theory Based on the Quasicrystalline Approximation (QCA/DMRT)
TL;DR: A model for the microwave emissions of multilayer dry snowpacks, based on dense media radiative transfer theory with the quasicrystalline approximation with the QCA, provides more accurate results when compared to emissions determined by a homogeneous snowpack and other scattering models.
Journal ArticleDOI
Electromagnetic Scattering by Bicontinuous Random Microstructures With Discrete Permittivities
TL;DR: The NMM3D results indicate that the scattering by the bicontinuousmedium with a broader size distribution has a weaker frequency dependence than that by the medium with a more narrow size distribution.
Journal ArticleDOI
Electromagnetic Computation in Scattering of Electromagnetic Waves by Random Rough Surface and Dense Media in Microwave Remote Sensing of Land Surfaces
TL;DR: The electromagnetic full-wave simulations for scattering of waves by soil surfaces, bistatic scattering, backscattering, and emissivity which are signatures measured in microwave remote sensing are reviewed.
